Meanwhile, a Kalamazoo Department of Public Safety lieutenant said police are looking for a witness or witnesses to the Aug. 18 assault to come forward in hopes of identifying the man's attackers.

“Nowhere near what I would like to see,” Lt. David O'Strander said when asked if police are still receiving tips in the case. “They've been slow in coming, I'll put it that way.”

O'Strander said detectives distributed fliers Wednesday at Wayside West in the 3400 block of Stadium Drive. The fliers described the attack and asked anyone with information to contact KDPS or Silent Observer, the lieutenant said.

Police have said four to six men fled the scene following the incident, which was reported just before 2 a.m. When officers arrived at the bar they were told by a man at the scene that he and the critically injured man, whose name has not been released, had been inside the bar with another acquaintance and were leaving and walking through the parking lot when a verbal exchange that began with another group of men became violent.

The man told police he was knocked to the ground and the critically injured man was knocked to the ground and punched and kicked several times. Police said the man had severe head trauma when he was taken to Bronson Methodist Hospital.

The suspects in the assault were last seen leaving Wayside in a tan- or brown-colored sport utility vehicle and headed east on Stadium Drive. Investigators have said that not all members of the group were involved in the assault of the two men.

O'Strander said Thursday that someone coming forward to police “would certainly help” police in their investigation.

Police ask anyone with information about the incident to call KDPS at 269-337-8139 or contact Silent Observer at 269-343-2100 or www.kalamazoosilentobserver.com.
